T o all ioho'ln it may concern Beqit'known that-I, JOHA-NNES' TH. PEDER- sin,- a citizen of the UnitedSt-ates, residing at Flushing,,borough of Queens-city and :State of. NeW Y ork, have" inventedj an .1111 f proveinent. in "Coffee Urns, of whic'hthe fol-g lowing is a: specification. g i lhis i vention relates to coffee ur ns and more particularly to that type of cofiee urn in which there isincl'uded an apparatus for passing the coflee'ztrom the? bottoinfo'f theurn to the; top 'the're'ofand to provlde in such apparatus a devicefor distributing the' liquid in order to cause itto "pass as uniformly as possible through the ground 'coflee in the making ofthe'beverage. Here tofo're, in coffee urns of. this type the co'fie'e has been-passed fromthe-bottorn to the top of the urnby a suitable pump caused ,toforce the. liquid through pipe which may 1 also include agauge and to. deliver the coffee in a substantially uniformstream to the'top of the-urn. In this apparatus obviously the liquicl'is not evenly distributed and the entire, 'oriat least the best results cannot beobtained iii-making the coffee. v In carrying outv the invention to overcome this difliculty I employ an aerator in the upper part of the urn and; this aerator device is placed at the discharge 'end' of the system for causing the flow of the liquid S0935" to distribute the 'sa'ine evenly over the ground 1 coffee in 'theurn ini o'rder' toutilize all of the best and most economical'resu ltsin melting; the beverage. V I I The aerator apparatus for the 'coifee'urn asfmade inra'c'cordance with this invention will be hereinafter more-part'icul'arly described in conjunction'with'the accompanying drawings, in Which, V

The apparatus to which my .invention more particularly relates consists of. an aerator device more particularly illustrated in Figs. 2 and-6 oi the drawing. This comprises a.vessel 37 having its bottom perforated. or made of a materialot suitabie mesh as indicated at38 and fitted with a cover 39. A suitable pipe eh) extends into the vessel 37 and is turned upwardly therein in order .to have its orifice located in an approximately central position therein. Surrounding the discharge end of the pipe there is a distributor disk 41. Exteriorly of the vessel 37 there is a pipe connection 42 suitably connected thereto and torming afcontinu'ation of the pipe 40; or as will be understood these parts may be made an integral structure. and caused to pass through and to be suitably connected to the walls of the vessel 37 The pipe connection 42 is suitably connected to a pipe connection 43 by a hinged joint A or otherwise and the pipe connection 43 is connected to the walls of the urn to form a. continuation of the horizontal portion of the elbow 29. As illustrated the pipe connection 12 terminates in an offset semi-spherical head 45 in which there is a centrally disposed stem .46, and similarly the pipe connection terminates in a semi-spherical head 17 in which there is a centrally disposed stem 4.8. This stem 48 is adapted to pass through the stem 46 and is screwthreaded interiorly to receive a set screw 49 by which the semi spherical heads are connected\vith an intervening, washer 50 which preferably madeot metal and suitably perforated in order .to torm the hinged joint as hereinbet'ore described. As illustrated the pipe connection 43 is secured to that portion of the horizontal member of the elbow 2!) extending through the body of the urn by a set screw 51 or otherwise. 7 n

It will now be apparent that in making coffee with the urn, as hereinbetore described, the liquid as caused to flow from the,bottom to the top of the urn by the use of the pump will pass through the pipe 28, the elbow 29 and be delivered to the aerator device'in theupper portion of the urn and the pressure under which the liquid isdelivered while relatively small is sufliciently great to cause the larger portion of the coffee to be projected against the inner surface of the coverand to flow down the sides of the same in all directions so as to be evenly distributed to the groundcoffee as contained in the strainer bag 15. Manifestly alsoa relatively small portion .ofthe liquid will flow down over the distributor disk 41 and this portion of the liquid will be evenly distributed from the periphery of'the disk. It will also be apparent that by removingthe cover 12 the aerator device may be turned from the position it assumes in use as illustrated in full-lines, Fig. 2 to a position at right angles thereto,

and in this latter position the samc will f in no "wise interfere .with the removal of the strainer bag from th m-n or the, clean-V ing of the urn and also makes it possible ,ltwwill to readily clean the aerator device.

also be apparent that the. vapors arising fromthe liquidzin the body member of the urn will ,accuniulatein the upper portion of the body. member includingthat part thereof in which the aerator vessel is located so that these vapors and the aroma of the coffee which they carry, or at least a large ceptacle to the upper portion ofthe' body member, a vessel connected to the discharge end of the said pipe connections within the body member, and means associated with the vessel for causing a distribution of the liquid in the upper portion of the body 1 member for its return to. the beverage receptacle. 1
